In EU sources written before the prequels, the term "President of the Senate" was used to refer to the leader of the Old Republic; when the prequels revealed the Republic's leader to be called the Supreme Chancellor, "President of the Senate" was retconned to be one of the Chancellor's titles. However, The Essential Chronology and The New Essential Chronology have both identified the leader of the Senate during Ulic Qel-Droma's trial as President of the Senate, adding some confusion. The Databank article on Ulic Qel-Droma describes the President as Supreme Chancellor.
